2.3.0.108_canary_2026-07-20

This release is a canary release intended to be used for testing.

If no major faults are found, this release is intended to be the basis of the next beta release.

MS365 subsites and shared mailboxes

This release improves the Microsoft 365 backup support with two additions.
Support for backing up SharePoint subsites has been added, making it possible
to include sub-sites beneath a site collection in a backup.

The handling of shared mailboxes has also been improved, with better detection
and enumeration of shared mailboxes within a tenant.

The license counter now excludes shared mailboxes without a license, and supports
top-level filtering of users/sites/groups based on classification.

An extra information button is added to the source page that shows a summary
of what content was found in the MS365 tenant.

Case-insensitive remote filename matching

A new option has been added to perform case-insensitive matching of remote
filenames. This helps with backends that do not preserve filename casing, and
prevents issues where files cannot be found because of case differences.

Improved filter parsing

The filter parsing logic has been improved to handle more edge cases and
produce more predictable results when building filter expressions.

Added wipe-encryption to database tool

The database tool now supports a wipe-encryption command that can be used to remove all encrypted fields from a server database. With this command it is possible to get an encrypted database back into a state where it can be opened again. After encrypted fields are wiped, the user can then edit backups and settings to replace the lost data.

Was able to revert back to using the insecure-permissions.txt file so I’m back to normal service.

From .107:

So as it was paused after upgrading I retried a delete+create on the database and their was no message about the pause, however other than the database placement turning red, there is zero evidence that it’s running, and nothing in any UI or event logs. I have no idea if something is running.
